IMPROVEMENT IN KEROSENE-BURNERS.

Specification forming part of Letters Patent No. 44,44 1, datedSeptember 27, .1864.

To all whom it may concern.-

Be, it known that I, GEORGE NEILsoN, of Boston, in the county ofSufl'olk and State of Massachusetts, have invented anew and usefulImprovement in Kerosene Burners and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being bad to the accompanyingdrawings, forming a 1-art of this specification, in which- Figure l is avertical central section; Fig. 2, atop view, with the cap removed andFig. a perspective view of a portion of the wicktube.

Like parts are indicated by the same letters hall the drawings.

The nature of my improvement consists in extending the deflecting-conefrom the base of the case or shell to the top of the wick-tube, for thepurpose of passing pure currents of atmosphere directly into the flame,and entirely preventing the escape of gases or vapors into the room.

To enable others skilled in the art to make and use my improvement, Iwill now describe its construction and operation.

A is the wick-tube, fastened gas tight into the bottom (I of the shellor case, B, which is attached to the top of a lamp by means of the screwaim the usual manner. That portion of the wick-tube opposite thespur-wheels or lifters G is out out, as represented in Fig. 3, so as tol a e a rectangular strip, e, attached to the in ain body of the tubeonly at one end, thereby forming a yielding surface or spring, by meansof which the wick, whether thick or thin, is always pressed suflicientlyhard against said lifter to prevent them from slipping.

In place of the spring 0, constructed as described, it is obvious thatvarious other kinds of springs may be employed and produce the sameresult.

B is the base of the case or shell, to which the upper portion, K, ispermanently attached by indentation, soldering, or brazing.

d is the deck or bottom of the shell, and c is a screw by means of whichthe burner is attached to the top of a lamp.

ff are small perforations in the side of the base B, through whichcurrents of fresh air pass up into the deflectingcone J, as representedby the arrows in Fig. 1. The conical deflector J (the shape and positionof which are shown in Figs. 1 and 2) extends from the base of the shellto the top of the wick-tube, being firmly secured at its bottom to thebottom of the upper portion of the shell K.

m m are small perforations, through which pure currents of air pass up,as shown by the arrows in Fig. 1, and impinge upon the flame.

P is the removable cap, of the usual construction.

M is a spring-fastener for holding the glass chimney in place.

I is the vapor-tube, soldered air-tight to the bottom of the base, asshown in Fig. 1, and extending upward nearly to the top of the wick-tubeand deflector, forming the only conductor of vapor from the lamp to theflame, and as this tube extends upward between the wick-tube anddeflector, so near to the blaze, all the vapor from the lamp forced bythe upward current of heated air impinges directly upon the flame, andconsequently can never escape unburned into the room, my invention beingin this respect a great improvement over any other with which I amacquainted for a similar purpose.

My burner is very simple, cheap, and pro duces a perfectly inodorouslight, it being practically impossible for any unburned gas or vapor toescape into the room-an object never before effectually attained inkeroseneburners.

Having thus described the construction and operaton of my invention,what I claim as new, and desire to secure by Letters Patent,

Extending the conical deflector J from the top of the wick-tube down tothe base of the shell, and attaching it thereto, substantially as andfor the purpose described.

GEO. NEILSON.
